Hello everyone. So i started learning about electronics slowly, my physics knowledge is really bad but i hope i can fix that.
This is my second electronics project so i decided to do something cool... http://www.electro-tech-online.com/imgcache/8472-14.gif
I end up doing this, i have no idea how it works and i barely connected everything to my breadboard.
I use 9V power source
3,5V , 0,02A 10leds
10k potenciometer
and 1k(didint have 1,2k) resistor exactly as shown in the scheme.
everything seemed to work fine but when i play music only 5 or 6 leds are glowing and the last 4 are not doing anything ;/ Whats should be wrong?
I tryed to read lm3915 description but there is so much information my head almost blew up :/ there is no way i can understand something with brains like mine, so i hope u got some simple explanation how to fix that
